This song uses several math concepts and unless the children are familiar with them, parts of the song won’t make sense. Before using this song, review it and make sure the concepts used have been taught to the children. The concepts include single number comparison as well as fact families and tens. -- Mar. Harman

Let’s compare numbers,
if they’re bigger, smaller or the same.
Greater than for bigger,
less than for smaller, |
equivalent or equal.
Let’s play the game!
5 6. Five’s less than 6.
5 4. Five’s greater than 4.
5 5. They’re equivalent. Come on. Let’s do some more.
